I've talked about this smartphone app quite a lot, and it is one of my favorites to use. How fast they pay is one good reason why I like them so much! You use it while you are out shopping. They have a lot of products listed on their offer wall, mostly grocery products, and if you buy those while you're out, you can upload your receipt to Ibotta and they'll pay you back some actual cash for proving you bought the item(s). You only need $20 to get paid to Paypal, and they send it almost instantly after you request it.
What has made PayPal so popular among both consumers and merchants, or clients and contractors, in this case, is that it is secure, allows for international payments and payments can be received almost instantaneously. When someone sends you a payment it arrives in your PayPal account within minutes compared to days when receiving an ACH deposit in your checking account or check by mail.
